Background
Introduction
Diffusion-weighted MRI (DWI) has been applied to extracranial sites since the 1990s (1).
The advent of echo-planar imaging (EPI),
high-gradient amplitude and multichannel coils,
and parallel imaging have been instrumental in allowing fewer motion artifacts and high-quality prostate images.
The acquisition time of DWI in the prostate is short,
and it does not need the administration of contrast media.
Thus,
DWI can be included easily in routine imaging protocols.
We review the basic concepts for the biologic basis of DWI and techniques of prostate 3-T DWI and clinical application of MRI in localized prostate cancer (PC),
potential uses of DWI in:
• Prostate cancer detection (tumour localization and prognostication).
• Staging of Prostate Cancer.
• Recurrence Risk and Treatment of Prostate Cancer.
• Implications in the planning of radiation therapy.
• Monitoring treatment after radiation therapy (RT) and hormonal therapy (HT).
• Detection of local recurrence after RT,
HT or radical prostatectomy.
